[Histonet] nissl stain

[Smith, Allen]

A good Nissl stain stains only RNA, but some "Nissl stains" also stain DNA.
It's easy to tell the Nissl bodies from the nuclei, because they are smaller
and irregular.  Since Nissl bodies have high concentrations of RNA, they
stain darkly.  Nissl bodies are characteristic of neurons with long axons.
Since neurons with short axons and glial cells have low concentrations of
RNA, they stain weakly, if at all.
